Effect the Technique of Light Trapping on the Performance of Simple Junction n-p Solar Cells Based on GaAs and Si [PDF]

open access: yesЖурнал нано- та електронної фізики, 2017
Light trapping enhances the absorption of active materials in photovoltaic cells. The use of light trapping results in a thinner active region in a solar cell, which lowers the production cost by reducing the amount of material used, and increases the ...

Disorder Improves Light Absorption in Thin Film Silicon Solar Cells with Hybrid Light Trapping Structure

open access: yesInternational Journal of Optics, 2016
We present a systematic simulation study on the impact of disorder in thin film silicon solar cells with hybrid light trapping structure. For the periodical structures introducing certain randomness in some parameters, the nanophotonic light trapping ...

Radiation trapping in coherent media [PDF]

open access: yes, 2001
We show that the effective decay rate of Zeeman coherence, generated in a Rb87 vapor by linearly polarized laser light, increases significantly with the atomic density. We explain this phenomenon as the result of radiation trapping.

Solar Cell Light Trapping beyond the Ray Optic Limit [PDF]

open access: yes, 2012
In 1982, Yablonovitch proposed a thermodynamic limit on light trapping within homogeneous semiconductor slabs, which implied a minimum thickness needed to fully absorb the solar spectrum.

Scalable simple liquid deposition techniques for the enhancement of light absorption in thin films: Distributed Bragg reflectors coupled to 1D nanoimprinted textures

open access: yesAIP Advances, 2017
Light trapping within a light absorbing medium is a key to highly efficient thin film solar cells. We propose a large-scale procedure based on materials with low absorption for the fabrication of combined Distributed Bragg Reflector (DBR) and grating ...

Coherent population trapping in quantized light field [PDF]

open access: yes, 2005
A full quantum treatment of coherent population trapping (CPT) is given for a system of resonantly coupled atoms and electromagnetic field. We develop a regular analytical method of the construction of generalized dark states (GDS). It turns out that GDS

Light-trapping modes in lossy plasmonic waveguides

open access: yesAIP Advances, 2019
Light-trapping modes can exist in lossless plasmonic waveguides. Here, we investigate the effect of metallic loss on light-trapping modes using the usual complex wave vector (β)-real frequency (ω) formulation and an alternative real β-complex ω ...
